Coffee
Drinking up to four cups of coffee a day carries no health risk, experts say. Scientists said those who stick to that limit have no need to worry,” reports The Sun.
Coffee is rich in both antioxidants and polyphenols and it is these properties that give some beneficial benefits.
Coffee consumption has been linked to lower risk of cardiovascular disease, liver cirrhosis, diabetes, cancer(especially prostate cancer), coronary heart disease and Parkinson’s.
A recent study at Southampton University found that 3 cups a day lowered the risk of dying from a stroke by 30%, liver cirrhosis by 39% and coronary heart disease by 19%.
The 90+ Study found that the longest living people enjoyed 2-4 cups of coffee a day.
One thing to keep in mind is that caffeine may slightly raise blood pressure in some people. However, this effect is generally small (3–4 mmHg) and tends to fade for most individuals when they consume coffee regularly.
Caffeine is also addictive and some people suffer side effects linked to excess intake which may include anxiety, restlessness, tremors, irregular heartbeat and trouble sleeping. Caffeine can take 4-7 hours to metabolise so it is best not to drink coffee late in the day.
Coffee is also a diuretic which means it makes you want to urinate more frequently. So bear this in mind if you have bladder problems.
